The filmmaker plans to begin making the film in 2016. John Hodge, who wrote the screenplays for Boyle's Trance, Trainspotting, Shallow Grave and A Life Less Ordinary, is currently working on the script.

"There's always been this long-term plan for Trainspotting 2, if John can produce a decent enough script, I don't think there will be any barriers to Ewan or any of the cast coming back. I think they'll wanna know that the parts are good so they don't feel like they are letting anyone down."

Boyle's next film Trance - which stars James McAvoy and Rosario Dawson - will open in the UK on March 27 and in the US on April 5.
